老朽化した砂防関係施設の健全度及び対策優先度に関する定量的な評価手法の提案

抄録

To prevent sediment disasters such as debris flows and landslides, it is important to characterize the damage that occurs to SABO facilities, and to carry out effective maintenance. Administration of these facilities requires monitoring of all damage, as well as evaluation of the soundness of the structures, in order to determine the greatest priority for engineering work. However, no method currently exists to evaluate soundness or to assess priority of engineering work for damaged SABO facilities. Here we describe a quantitative evaluation method for determining the soundness and maintenance priority of SABO structures, which takes into account budgetary limitations. We discuss our approach using the example of a bridge in Europe, and describe the details of this specific case as well as identify directions for future work.
